Abstract

A universal sweep plow configured to mate securely and be attached to a seed boot. The universal sweep plow includes sweep plow attachment formed from a single unit of metal and an anchor. The attachment includes a central portion configured to mate with a seed boot and right and left central portion openings configured to align with an anchor hole in the seed boot. The right and left wing portions extend outward and rearward from the central portion. The anchor is configured to attach the sweep plow to the seed boot by passing through the right and left central portion openings and the anchor hole in the seed boot.

a universal sweep plow configured to mate securely and be attached to the seed boot, the universal sweep plow including;

a sweep plow attachment, the attachment including;

a central portion received in the recess of the seed hoot in a mating relationship, the central portion including right and left central portion openings configured to align with an anchor hole in the seed boot such that at least a portion of the central portion is configured to be positioned between the pair of spaced-apart shoulders, and

right and left wings extending outwardly and rearward from the central portion, each wing including a linear leading edge extending along an axis which intersects the seed boot at a location rearwardly of the leading edge of the seed boot, a linear trailing edge generally parallel to the leading edge, and a generally V-shaped outer edge interconnecting the leading and trailing edges, the V-shaped outer edge of each wing including;

a linear trailing outer edge portion projecting from the trailing edge at an obtuse angle thereto; and

a linear leading outer edge portion projecting from the leading edge, the trailing outer edge portion and the leading outer edge portion intersecting at a wing tip located forwardly of at least a portion of the trailing edge; and

an anchor configured to attach the sweep plow to the seed boot by passing through the right and left central portion openings in the central portion of the seed boot attachment and the anchor hole in the seed boot, such that the sweep plow attachment is held securely in place to the seed boot by a combination of the spaced-apart shoulders and anchor connection.

8. The agricultural implement of claim 7, wherein the wings extend outwardly from the central portion in a common plane.

9. The agricultural implement of claim 8, wherein a front edge of each wing is relatively lower than a rear edge of each wing such that the sweep plow acts as a soil engagement mechanism during operation.

10. The agricultural implement of claim 7, wherein each wing has a thickness and wherein the thickness of each wing is greater at a location adjacent the central portion relative to the thickness of each wing at a location spaced from the central portion.

11. The agricultural implement of claim 7, wherein the seed boot includes a seed boot point having a thickness and wherein the central portion of the sweep plow attachment has a thickness, the thickness of the central portion being generally equal to the thickness of a trailing edge of the seed boot point such that the seed boot point and central portion present a flush surface when the sweep plow attachment is attached to the seed boot.

12. The agricultural implement of claim 7, wherein the central portion of the sweep plow attachment includes an inner surface defining the cavity, the inner surface of the central portion being configured to form a mating relationship with the corresponding seed boot surface which includes a leading edge of the seed boot.

13. The agricultural implement of claim 7, wherein at least a portion of the central portion abuts each of the shoulders.

14. The agricultural implement of claim 7, wherein the central portion includes an upper edge abutting a first of the pair of spaced-apart shoulders and a lower edge abutting a second of the pair of spaced-apart shoulders.
